Abstract: A refrigerator includes: a storage chamber configured to store food; a cooler configured to supply cold into the storage chamber; a tray defining an ice making cell, which is a space in which water is phase-changed into ice by the cold; a water supply part configured to supply the water into the ice making cell; a temperature sensor configured to sense a temperature of the water or the ice within the ice making cell; a heater configured to supply heat into the ice making cell; and a controller configured to control the heater. The controller controls the heater to be turned on in at least partial section while the cooler supplies the cold so that bubbles dissolved in the water within the ice making cell moves from a portion, at which the ice is made, toward the water that is in a liquid state to make transparent ice. The controller variably controls the heating amount of the heater so that a rate at which the water inside the ice making cell is made into ice during an ice making process is maintained within a predetermined range that is lower than an ice making rate when ice making is performed while the heater is turned off. When a defrosting start condition is satisfied in the ice making process, the controller performs a defrosting process and reduces the amount of cold supply of the cooler.

Abstract: A refrigerator includes an ice maker, which includes an ice making cell, a heater configured to supply heat to the ice making cell during an ice making process, and a controller configured to control the heater. A cooling power of the cooler when a temperature sensed by a temperature sensor is greater than or equal to a limit temperature during an ice making process is greater than a cooling power of the cooler when the temperature is less than the limit temperature. A heating amount of the heater when the temperature sensed by the temperature sensor is greater than or equal to the limit temperature during the ice making process is greater than a heating amount of the heater when the temperature is less than the limit temperature.

Abstract: A refrigerator includes: a storage chamber in which food is stored; a cold air supply means for supplying cold air to the storage chamber; a tray forming an ice-making cell; a heater for supplying heat to the tray; and a controller for controlling the heater. The controller turns on the heater in at least a part of a range in which the cold air supply means supplies cold air such that air bubbles dissolved in water inside the ice-making cell can move from ice-generating parts to liquid-state water, thereby generating transparent ice. The controller determines whether or not the heater is functioning abnormally in the ice-making process. If it is determined that the heater is functioning abnormally, the controller supplies water to the ice-making cell by a second amount of water supply, which is smaller than the first amount of water supply, during the next water supply process.
